Docker Git 插件中的 Jenkins 允许本地结帐

【问题标题】：Jenkins in Docker Git Plugin allow local checkoutDocker Git 插件中的 Jenkins 允许本地结帐

【问题描述】：

有人问过同样的问题，但 Docker 容器中的 jenkins 没有 Jenkins: allow local checkout

我让 jenkins 在 docker 容器中运行，并且能够毫无问题地执行管道作业。 最近在新机器上安装容器后，我得到：

ERROR: Checkout of Git remote 'file:///usr/src/' aborted because it references a local directory, which may be insecure. You can allow local checkouts anyway by setting the system property 'hudson.plugins.git.GitSCM.ALLOW_LOCAL_CHECKOUT' to true.
ERROR: Maximum checkout retry attempts reached, aborting
Finished: FAILURE

我在 init.d 中试过这个脚本

import jenkins.model.Jenkins
import java.util.logging.LogManager
/* Jenkins home directory */ 
def jenkinsHome = Jenkins.instance.getRootDir().absolutePath
def logger = LogManager.getLogManager().getLogger("")
/* Replace the Key and value with the values you want to set.*/
/* System.setProperty(key, value) */
System.setProperty("hudson.plugins.git.GitSCM.ALLOW_LOCAL_CHECKOUT", "true")
logger.info("Jenkins Startup Script: set GitSCM.ALLOW_LOCAL_CHECKOUT to true . Script location : ${jenkinsHome}/init.groovy.d ")

我在 docker 容器中试过这个

在詹金斯系统属性中我看到hudson.plugins.git.GitSCM.ALLOW_LOCAL_CHECKOUT true

问题依然存在 运行 Jenkins 2.332.3

VOLUME /var/jenkins_home

问题依然存在： 有什么想法可以解决这个问题吗？ 有什么方法可以让我的 git 目录不是“本地目录”？

【问题讨论】：

    标签： jenkins jenkins-pipeline


    【解决方案1】：

    我的答案在 init.groovy.d/dev/jobs.groovy 文件中

    在这一行之后：

    def scm = new GitSCM("file:///usr/src/");

    我添加了这一行

    scm.ALLOW_LOCAL_CHECKOUT=true

    【讨论】：

      【解决方案2】：

      我也偶然发现了这个问题。基于这个answer，只需要在启动容器的时候加上env变量即可。

      docker run ... --env JAVA_OPTS="-Dhudson.plugins.git.GitSCM.ALLOW_LOCAL_CHECKOUT=true"
